VALVE.

SPECIFICATION forming part efvnettersy Patent No. 732,669, dated June 3o, 1903. Application tiled December 17, 1902. Serial No. 135,533. (No model.)

To a/ZZ whom t may concern/.-

Be it known that I, EDWARD WALTHER, a citizen of the United States, residing at Washington, in the county of Washington aud State of Iowa, have invented new and useful Improvements in Valves, of which the following is a specification.

My invention relates to valves; and the object of the same is to construct a device comprising an inlet and an exhaust valve connected tothe opposite arms of aTand provided with automatically-operated intermittent means for carrying the valves quickly from one eX- treme position to the otherthat is, from full supply to full cut-ott.

The simple and novel construction employed by me in carrying out my invention is fully described and claimed in this specification and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is a vertical longitudinal section of my device. Fig. 2 is a side elevation of the same attached to a pumping-bell. Fig. 3 is a horizontal section taken on the line 3 3, Fig. .1.

The numeral 1 designates a supply-valve, and 2 an exhaust-valve. As these valves are practically identical in construction but one will be described in detail, but the same numerals of reference will be applied to the like parts of the other. The valve 1 has a casing 3, provided with an upper detachable head 4 and a lower detachable head 5. rlhe casing 3 is divided into two compartments 7 and 8 by a transverse partit-ion 6, having perforations 9 therein and a seat 10, formed on the under side thereof and inclosing theperforations. Avalve-plunger 11 is mountedin the lower compartment 7 of the casing 3. The

-plunger 11 is beveled on the edges to a knifeedge 12 to prevent covering an annular inlet-port 13, formed in the walls Vof the casingl rconnection 17 via the annular port13, and the chamber 8 communicates with a threadedv the connection 17 on the valve 1.

The connection 18 on thevalve 1 is coupled to one arm 2O of an'irregular T,the other arm 21 of which is coupled to the connection 17 on the valve 2. The stem 22 of the T is connected to a motorcylinder 23, mounted within abell 24. An exhaust pipe 25 is joined to the connection 18 on the valve 2.

connection 18. A supply-.pipe'19iis joined toy A standard 26 is located near the valves 1 and 2, andfnlcrumed on the standard is a lever 27, having oppositely-extending arms 28 and 29 of unequal length. The shorter arm 28 engages the slot 16 in the head 15 on the valve 2 and the longer arm 29 engages the slot 16 in the head 15 on the valve 1 and eX- tends therethrough and engages a slot 30 in the lower end of a downwardly-extending arm 31,*carried by the bell 24. The lever 27 has an enlarged portion 32 formed thereon, located just over the standard 26. A recess 33, having two opposed straight walls 33 and two opposed diverging walls 33h, is formed in the enlarged portion 32, andpivotally mounted within said recess is an arm 34, which is constructed to swing through an angle of about twenty degrees in a vertical plane passarm 34 and enable it to operate the plungers 11.

Supposing the device to bein the initial po-k sitions (shown in Fig; 1,) water can then flow from the supply-pipe 19, through the annular Y port 13 into the chamber 7 of the valve 1, then upthrough the perforations 9 into the chamber 8, then through 'the pipes 2O and 22 into the motorcylinder 23, thereby raising the bell 24. The bell 24 will continue to rise until the lowerlend of the slot 30v engages and raises the `lever-arm 29 high enough to swing the arm 34 and bob 35 far enough to'bring the center of gravity to the left of the standard 26, when the arm 34 will swing tothe left'and I ICQ.

the arm 28 will come in contact with the bottom of the -slot 16, unseating the plunger 11 of the exhaustvalve 2.

The flow of water through the valve l into the motor-cylinder 23 will then be cut off; but the exhaust will be open, and water will flow out of the motor-cylinder 23 via the pipes 22 and 2l, port 13 into chamber 7 of valve 2, up through perforations 9, and through chamber 8 and exhaust -pipe 25 to the open air. The outflow of the water from the motor-cylinder 23 will permit the descent of the bell 24, which will continue until the upper end of the slot in the arm 3l engages the arm 29 and forces it down far enough to displace the arm 34 and again operate the valves l and 2.

It should be noted that the plungers ll of the valves 1 and 2 are moved from one extreme position to another by the action of the inverted pendulum comprising the arm 34 and weight 35, the slots 16 being made long enough so that the arms 2S and 29 do not engage the heads l5 until the arm 34 swings over. Since the plunger 11 fits loosely the chamber 7, it will stay wherever put-that is, it will not be displaced by the pressure ofthe water, which is equal on both sides, unless the plunger is seated, in which case it will be held seated by the water-pressure.

While I have specified water as passing through my valve, any other fluid or gas would operate in precisely the same manner.

I do not wish to be limited as to details of construction, as these may be modiied in many particulars without departing from the spirit of my invention.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a valve mechanism, an inlet-valve provided with a slidingly-mounted plunger having a slotted stem, an outlet-valve provided with a slidingly-mounted plunger having a slotted stem, a lever fulcrumed intermediate its ends with its oppositely-extending arms loosely engaging said slots, an upwardly-extending arm pivotally connected at its lower end to said lever free to swing through a small arc and a slotted arm loosely engaging said lever to intermittently operate said lever to displace said arm to swing over from one extreme position to the other to operate said valves, substantially as described.

2. In a valve mechanism, the combination of an inlet-valve provided with a slidinglymounted plunger having a slotted stem, au outlet-valve provided with a slidingly-mounted plunger having a slotted stem, a lever having oppositely-extending arms engaging said slots and bearing an upwardly-extending pivoted arm free to swing and stops mounted on said lever located to limit the swing of said arm, said slots being of sufficient length to permit said lever to swing through a considerable arc before engaging their ends to operate said valves, and means for operating said lever to displace said arm from its position of repose against one of said stops and strike the other of said stops to operate said lever and said valves, substantially as described.

3. In a valve mechanism, an inlet-valve casing containing a valve-seat, a supply-pipe conneoted to said casing below said seat, a plunger mounted in said casing below said seat, an outlet-valve casing containing a seat, a plunger mounted in said outlet-valve casing below said seat, an exhaust-pipe connected to said outlet-valve casing above said seat, and a T one arm being connected to said inlet-valve above the said seat therein and the other being connected to said outlet-valve below said seat therein, and means for operating said plungers simultaneously and oppositely, substantially as described.

4t. In a valve mechanism, the combination ofa lever fulcrumed intermediate its ends, valves bearing stems having elongated slots therein through which said lever extends to intermittently :operate said valves, an upwardly-extending pivoted arm, stops carried by said lever and located on opposite sides of the fulcruxn to limit the swing of said arm about its pivot, and means for operating said lever to displace said arm, substantially as described.

5. In a valve mechanism, the combination,

"of an inlet-valve, an outlet-valve, a lever fnlorumed intermediate its ends and located to operate said valves in unison, a pivoted upwardly-extending arm, stops carried by said lever and located on opposite sides of the fulcrnm to limit the swing of said arm, and an arm having an elongated slot therein loosely engaging said lever to operate said lever in both directions to displace said arm to actuate said lever to operate said valves, substantially as described.

G. In a valve mechanism, an inlet-valve casing containinga valve-seat, asupply-pipe conneeted to said casing below said seat, a plunger mounted in said casing below said seat and having a slotted stem, an outlet-valve casing containing a seat, a plunger mounted in said outlet-valve casing below said seat and having a slotted stem, an exhaust-pipe connected to said outlet-valve casing above said seat, a T one arm being connected to said inlet-valve above the said seat therein, the other arm being connected to said outletvalve below said seat therein, and a lever engaging said slotted stems to operate said plungers simultaneously and together, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
